pfam16344: FecR_C (This model is not part of the current CDD release)
FecR, C-terminal
This domain is found at the C-terminal of FecR, which adopts a secretin N0-like fold. FecARI are responsible for induction of the ferric citrate uptake system. When ferric citrate binds FecA, a signal is transmitted across the outer membrane to FecR, a cytoplasmic membrane protein that transmits signal across the membrane and activates the sigma-70 family protein FecI.
